SED2 VFD Operation & Maintenance Manual

Dependency: First, set P0011 ("lock") to a different value than P0012 ("key") to prevent changes to user-defined parameter.
Then, set P0003 to 0 to activate the user-defined list.
When locked and the user-defined parameter is activated, the only way to exit the user-defined parameter (and
view other parameters) is to set P0012 ("key") to the value in P0011 ("lock").
Note: Alternatively, set P0010=30 (commissioning parameter filter=factory setting) and P0970=1 (factory reset) to
perform a complete factory reset.
The default values of P0011 ("lock") and P0012 ("key") are the same.
